Chen Hetu took the wooden sign and took a look at it.

This wooden sign is elongated, one side is uneven, and the other side looks like a ghost painting. As Yun Xiaoyue said, it is difficult to tell whether it is words or paintings.

Shen Tianlu leaned his head, pointed at the ghostly drawings on the wooden sign and said, "The ancient characters are written on it."

"Ancient writing?" Chen Hetu tilted his head and looked at Shen Tianlu.

Shen Tianlu said: "According to legend, this kind of writing was commonly used by people 1,500 years ago, but it disappeared later for unknown reasons."

Chen Hetu nodded thoughtfully, remembering that in the original world, those ancient characters also had many types. However, through the inheritance of culture and the precipitation of history, they gradually evolved into today's simplified characters.

"Then do you recognize the words on this?" Yun Xiaoyue came over and asked.

She originally thought that the wooden sign was a painting, but she didn't expect that it was actually words.

This surprised her.

Shen Tianlu nodded and said, "We know you!"

"Then what are the words on it?" Chen Hetu and Yun Xiaoyue asked in unison.

"Guanghan Palace!" Shen Tianlu said word by word.

Chen Hetu and Yun Xiaoyue both looked surprised.

They never thought that something like a ghost drawing talisman turned out to be the three characters Guanghan Palace.

Shen Tianlu continued: "If I guessed correctly, this wooden sign should be the key to entering the Guanghan Palace in the human world."

"The key to get in?" Chen Hetu glanced at the square sign in his hand again. No matter how he looked at it, he couldn't tell that the wooden sign was a key.

Yun Xiaoyue took the wooden sign from Chen Hetu's hand and looked around, feeling incredible.

Shen Tianlu smiled, then pointed to the uneven side of the wooden sign and said, "Look at this side of the wooden sign. It is uneven, similar to the teeth of a key. It needs to be inserted just right before it can be turned."

After Shen Tianlu said this, Chen Hetu and Yun Xiaoyue felt more and more that this square wooden sign looked like a key.

Shen Tianlu continued: "Look at the material of this wooden sign. It is not an ordinary material at all. Although I can't remember what this material is called, I know that this material is not afraid of water or fire, let alone swords.

"

"Is it?"

Yun Xiaoyue put the wooden sign on the ground, then took out her sword and swung it lightly.

"Ding!"

The knife and the wooden sign collided, causing countless sparks to fly.

Then, Yun Xiaoyue picked up the wooden sign and took a look. There was not even a trace on it.

This shocked her.

You must know that her sword is no weaker than Chen Hetu's Dragon Song Sword. Although she did not use all her strength, the power of the sword was not weak at all. Unexpectedly, it did not leave any mark on the wooden sign.

"How is it? Do you believe it now?"

Shen Tianlu had regained his composure at this time, with a smile on his face.

Yun Xiaoyue's sword attack also proved that this wooden sign is genuine and is not afraid of fire, water, or swords.

"I believe it, I believe it." Yun Xiaoyue handed the wooden sign to Shen Tianlu.

Shen Tianlu handed it to Chen Hetu and said, "You should keep this wooden sign first!"

Chen Hetu nodded and placed the wooden sign in the ring space.

Then, Shen Tianlu said: "Now that we have found this wooden sign, we can be very sure that my guess is correct. Gu Qiangu should have entered the Guanghan Palace in the human world."

"Yes, he should have gone in." Chen Hetu and Yun Xiaoyue nodded.

"Now that it has been confirmed that Gu Qiangu has visited the Guanghan Palace on earth, and we have also obtained the key to Guanghan Palace on earth, the next thing we have to do is to find the location of Guanghan Palace on earth."

"As long as we find the location of the Guanghan Palace on earth, and with this wooden sign, we can enter and uncover its mysterious veil."
